Solution
The correct option is B Cave According to Southwick, the ecosystems which do not contain all the four components, i.e., abiotic components, producers, consumers, and decomposers are considered as incomplete ecosystems. The abyssal depth of sea and cave contain only consumers and decomposers, but no producers and are thus called as the incomplete ecosystems.
